A prostrate dwarf perennial herb of freely-draining soil, naturalised in sparsely vegetated sites subject to moderate disturbance. Habitats include sand dunes, cliffs, heaths, conifer plantations on sandy soils, old gravel workings, roadsides and disused railways. Reproduction is from seed, and sometimes from pieces of rooted stolon. Lowland.
This species was introduced to Britain as a wool contaminant and its spread into semi-natural habitats was often from woollen mills; it was first recorded in the wild in 1901. However, some colonies appear to have resulted from the dumping of garden refuse. It can be very persistent, and its spread continues in some areas.
Native of Australia and New Zealand.
